Why Do Some Cities Use Non-Hour UTC Offsets?

Most of the world runs on whole-hour offsets from UTC, but a handful of places use half-hour or even quarter-hour offsets. India and Sri Lanka run at UTC+5:30, Nepal at an unusual UTC+5:45, parts of Australia at UTC+9:30, and a few regions use 45-minute offsets. These quirks usually reflect history, geography or a deliberate choice to sit between two neighbours.

Half- and quarter-hour zones can be a headache for scheduling international calls and flights. The cities here all use one of these offbeat offsets; Adelaide runs at UTC+10:30.

Frequently Asked Questions: Cities With Non-Hour UTC Offsets

Which places use half-hour or quarter-hour time zones?

India and Sri Lanka use UTC+5:30, Nepal UTC+5:45, Iran UTC+3:30, parts of Australia UTC+9:30, and a few areas use 45-minute offsets such as UTC+8:45.

Why do some countries use unusual offsets?

Often to better match the Sun across a country, to sit neatly between two neighbours, or for historical and political reasons.

Does an unusual offset cause problems?

It can complicate international scheduling, since a meeting time may fall on an odd half- or quarter-hour in another country.
